Wow, great!

Anyway, one more question.  Should this work?

metakit.storage().getas('blah[x:S,y:I]').structure()
[]

Because this does:

s = metakit.storage()
s.getas('blah[x:S,y:I]').structure()
[Property('S', 'x'), Property('I', 'y')]
This is correct behavior in the current design.  Storages are not "kept 
open" by views.  Their cleanup causes all views associated with them to 
become empty.

Should access to orphaned views throw an exception?
That would indeed be another way to treat this (and probably useful to 
help detect incorrect use), but it would require some redesign of the 
C++ core.
